The Lowdown
Right, folks, Rusty here. Let's be straight with you about the local scene. We've got a tough stretch ahead. The whole 16-day window is a bit of a flat spell, with barely a ripple to get excited about. The forecast is pretty much one long gap of poor surf, so don't be holding your breath for any magic.
Looking at the charts, the first recommendation isn't really a standout at all. The best we can say is that from Thursday morning, August 6th, through to Friday afternoon, August 21st, it's virtually all "poor surf conditions." There are no days where the surf is worth paddling out for. The combined energy is tiny, with values staying under 50 for most of the run, which is weak all the way. The only real flicker of life comes on Friday, August 21st, when the afternoon sees a 5ft swell from the southeast, but it's a short period windswell at 6 seconds, and the wind is cross-onshore at 9 mph, making it choppy and messy. The combined energy finally climbs to 178, which is still only moderate, but the quality is rated as poor, so it's not a goer.
Kennebunk Beach is the only break in the data, and it's a sheltered spot that needs everything to line up. The water's running a bit colder than normal for this time of year, at 63°F, which is a degree or so below average. With the swell so small and the winds often onshore or cross, this place is not going to fire. Given the flat conditions and the beach setup, this is looking more like a spot for the kite surfers to get a wiggle on than a paddle surfer's dream.
Stick with it, folks. It tends not to stay this poor for too long, and forecasts can change.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
